Wondering if anyone can assist, I have an RB50, running 21.5, which has no power. It has the latest firmware, (1.4 I think it is) and at full throttle the rpm is very low. No timing or turbo boost can be heard either. Have tried a new sensor cable with no effect. Other thought was maybe I have incorrect settings on it? There was no attachment with firmware for revised hand held programmer settings, but maybe I have them set incorrectly. Perhaps someone can link me to the current sheet for the hand held unit so I can check against mine?

Thanks in advance.

Maybe have a look at your transmitter settings? Check your EPAs and direction. Some speed controllers require the throttle channel to be reversed.

Thats all ok, I have been using this complete setup for a little while. It has only now started to have problems.

I would be reconfiguring from scratch. reload firmware and reprogram end points, speedy settings etc. Swap out sensor cable and even try a different motor. The team wave speedys do have a reputation of failing though

Go back to the last firmware that you had. If then it does not work as it did before, more than likely the ESC is faulty.

Looks like the problem is a little more serious. When I connect the program card, the letters "er" appear.
